x-nAY APPARATUS.

. To all whom it may concern Be it known that I, HARRY F. 'VVAITE, a citizen of the United States, and a resident of the city of New York, county of Queens, and State of New York, have invented a new and useful Improvement in X-Ray Apparatus, of which the following is a specification.

The object of my invention is to provide a light and portable. X-ray apparatus, which may be placed in any desired position and may be used to any 'desired'extent without regard to climatic conditions or disturbances and without danger to any one from high tension feed wires or other high tension partsof the apparatus. A further objectv is to provide an apparatus in which the X-ray tube is immersed in oil and so are all exposed parts which are energized when the tube is in use so that under no circumstances can there be any leakage'of high tension current from one terminal to another, such as sometimes occurs when" such devices are placedin air.

These and other objects are accomplished by my invention one embodiment of which is shown in the annexed drawing, forming a part -hereof, in which the figure is at perspective, fragmentary view, .with the electrical connections shown diagrammatically:

My improved apparatus consists of a box .or casing 1 which is preferably made of metal and is oiltight, so that it will hold transformer oil-without leakage. Its top 2 is preferably made of fiber. The casing is lined with metal except at its center where it is provided withmetal slides 3 by means of which the opening for the X-raysgenerated by the; tubel may be regulated. The

casing, preferably has sufficient transformer oil therein to cover the tube 4 an inch deep,

as indicated by the line near the top of the casing 1. f K v The tube 4 is supported by suitable pedestals 6, one at each end, which rise from the bottom 7 of the box .1, and these pedestals carry wires which run to the anode 28 and hot cathode 29 respectively of the tube 1.

These wires are also connected "to the secondaries 8 and 9 resectively. These secondaries are energized y their primaries 10 and 11. The primaries are connected with an alternating current generator 12, or any other suitable source of power,- as fol= Specification of Letters Patent. Patented Mar. 23, 1920. I Application filed.

lows: One terminal 13 of this generator has a Wire-1l that runs to the primary 10, and this primary also is connected to. a wire 15 which runs to a regulating apparatus 16.

which is connected to a wire 17 that runs to the terminal 18 of thegenerator 12. A wire 19 connects the wire 14 to one terminal of the primary 11. The other terminal of this primary is connected to a wire 20 which runs to a regulating device 21 which is connected by a wire 22 with the Wire l 7 so that the primaries may be regulated independently. The secondary 8 has a wire 23 that runs to the anode 28 and another wire 2% which runs to the cathode 29. One terminal of the secondary 9 is connected to the wire 2 .1 and the other terminal ofthe secondary v 9 is connected by a wire 25 to the opposite terminal of the cathode 29; The current passing through the hot cathode 29 may be regulated through the controller 21.

The regulating apparatus 16 and 21 may be placed either in oron the box 1, or in 4 any other convenient location.

erated and passed out of the apparatus "through the oil and the fiber cover and the space between the slides 3. All stray rays fare intercepted by the metal of the box 1 I and the metal lining of the cover 2. ."When X-raysare no longer. needed, the apparatus may be shut off and disconnected in the .con-

ventional manner.

While I have. shown and .descrlbed, one

-embodintent'of my invention, it is obvious thatit is not restricted thereto, but is broad enough to cover all structures that come within the scope of the annexed claims.

' What I claim 1s:

1. In a'device of the class described, a

box,,.,oil" therein, an X-ray tube, a trans former immersedinsaid oil and means for up transformer, an X-ray tube having terminals, conductors directly connecting the high tension Winding of said transformer to the terminals of said tube, a container for said transformer and tube and a body conductors and terminals, and surround mg sa1d transformer and sa1d tube.
